<P>PROBLEM TO BE SOLVED: To provide a product life cycle management (PLM) system comprising a database storing 3D objects and relations between the objects. <P>SOLUTION: The PLM system provides a GUI suitable for displaying to a user graphical representation of a hierarchy of stored objects. The GUI is adapted, upon selecting of a displayed object by a user, to display objects related to the selected object. At a given level in the hierarchy, displayed objects are distributed according to a respective weight. The weight of a displayed object depends on the number of its descendants in the hierarchy, which are displayed in the graphical representation. The invention makes it possible to navigate a database of the PLM system, storing complex modeled objects groups through interrelated data. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
